Answer:

Option 2 and Option 3 are equivalent to 5-3 × [10x (6-2)]

Step-by-step explanation:

Option 2:

5-3 × [10x (6-2)] = 5-3 × [10x4] = 5-3 × 40 = 5-120 = -115

Option 3:

5-3 × [10x (6-2)] = 5-3 × 40 = 5-120 = -115

The maximum productivity is 2646 units per month and it occurs at 21 years of service.

To find the maximum productivity and the year in which it is achieved, we need to find the vertex of the parabolic function represented by the productivity function.

The vertex of a parabola in the form y = a[tex]x^{2}[/tex] + bx + c is located at the point (-b/2a, c - [tex]b^{2}[/tex]/4a).

In this case, we have:

M(t) = -3[tex]t^{2}[/tex] + 126t + 150

So, a = -3, b = 126, and c = 150.

The year of service, t, is restricted to the interval 0 ≤ t ≤ 40, which means that the maximum productivity will occur at either t = 0 or t = 40, or at the vertex of the parabola.

The x-coordinate of the vertex is given by -b/2a, which in this case is:

t = -b/2a = -126/(2(-3)) = 21

So, the maximum productivity occurs at t = 21 years of service.

To find the maximum productivity, we substitute t = 21 into the productivity function:

M(21) = -3[tex](21)^{2}[/tex] + 126(21) + 150 = 2646

By using the synthetic division we have find that the quotient of x³-4x²+7 divided by x-3 is x² - x - 3, with a remainder of 4.

To use synthetic division, we first need to set up the equation in the correct format. We write the coefficients of the polynomial equation in descending order, and then we include any missing coefficients as 0. In this case, the equation x^3-4x²+7 can be written as:

1x^3 - 4x² + 0x + 7

Next, we write the linear equation in the format (x-a), where "a" is the value being divided out of the polynomial equation. In this case, a = 3, so we write the linear equation as:

(x-3)

We start by copying the first coefficient (1) from the top row to the bottom row.

We then multiply this coefficient by the value of "a" (3) and write the result (3) under the next coefficient (which is -4).

We add these two values together to get -1, which we write under the 0 coefficient.

We then repeat this process by multiplying -1 by 3 to get -3, which we write under the last coefficient (which is 7). We add these two values together to get 4.

Our synthetic division table should look like this:

3 | 1 -4 0 7 | 3 -1 -3

-----------------------------

   | 1 -1 -3 4

The bottom row of the table shows the coefficients of the quotient, which are 1, -1, and -3. These coefficients form the quotient of the division, which can be written as:

x² - x - 3

The last number in the bottom row of the table (4) is the remainder of the division. This means that our original equation x³-4x²+7, when divided by x-3, has a remainder of 4.

The surface area of the two hemispheres combined is 100π square meters, and the volume of the two hemispheres combined is (500/3)π cubic meters.

The circumference of a great circle on a sphere is given by the formula C = 2πr, where r is the radius of the sphere.

In this case, we are given that the circumference of the great circle is 10π meters, so we can set up an equation:

10π = 2πr

Dividing both sides by 2π, we get:

r = 5

So the radius of the sphere is 5 meters.

When the sphere is cut in half, we get two equal hemispheres. The surface area of a closed hemisphere is given by the formula A = 2πr^2, where r is the radius of the hemisphere.

Since we are dealing with a radius of 5 meters, the surface area of one hemisphere is:

A = 2π(5^2) = 50π

Therefore, the surface area of the two hemispheres combined is:

2A = 2(50π) = 100π

The volume of a closed hemisphere is given by the formula V = (2/3)πr^3. Again, since we are dealing with a radius of 5 meters, the volume of one hemisphere is:

V = (2/3)π(5^3) = (2/3)π125 = (250/3)π

Therefore, the volume of the two hemispheres combined is:

2V = 2(250/3)π = (500/3)π

The difference would be 1-1/4= 3/4

The standard deviation of the given data is approximately 3.08.

To find the standard deviation of the given data (5, 6, 8, 13), we first need to find the mean (X) of the data.

Mean (X) = (5 + 6 + 8 + 13) / 4 = 32 / 4 = 8

Next, we calculate the deviations from the mean for each data point:

Deviation from the mean = Data point - Mean

For 5: 5 - 8 = -3

For 6: 6 - 8 = -2

For 8: 8 - 8 = 0

For 13: 13 - 8 = 5

Then, we square each deviation:

(-3)^2 = 9

(-2)^2 = 4

0^2 = 0

5^2 = 25

Next, we calculate the sum of the squared deviations:

Sum of squared deviations = 9 + 4 + 0 + 25 = 38

To find the variance, we divide the sum of squared deviations by the number of data points:

Variance = Sum of squared deviations / Number of data points = 38 / 4 = 9.5

Finally, we take the square root of the variance to find the standard deviation:

Standard deviation = √Variance = √9.5 ≈ 3.08

Therefore, the standard deviation of the given data is approximately 3.08.

Answer:

Step-by-step explanation:

The area of the square is given as 1134 m². Let's assume that the side length of the square is "s". Then, we can write the area of the square as s² = 1134. Solving for "s", we get s = √1134. The perimeter of the square is given by P = 4s. Substituting the value of "s", we get P = 4√1134. To simplify this expression, we can factor out the perfect square factor of 36 from 1134, which gives us 1134 = 36 x 31. Therefore, P = 4√(36 x 31) = 4 x 6√31 = 24√31. Hence, the perimeter of the square is 24√31 m.

The solution of the fraction is n = 2 (option c).

Now, let's consider the equation n/32 = 1/16, where n is a variable that we want to solve for. This equation tells us that the ratio of n to 32 is equal to the ratio of 1 to 16. In other words, if we divide n by 32, we get the same result as if we divide 1 by 16.

To solve for n, we can use algebraic techniques to isolate the variable on one side of the equation. One way to do this is to multiply both sides of the equation by 32, which gives us:

n = (1/16) * 32

We can simplify the right-hand side of this expression by multiplying 1/16 by 32, which gives us:

n = 2

7 groups of 2/7 is equivalent to the whole, which is represented by the number 2.

When we have 7 groups of 2/7, we are essentially multiplying the fraction 2/7 by the whole number 7. To perform this operation, we can use the following formula:

a/b × c/d = ac/bd

where a, b, c, and d are any numbers, and a/b and c/d are two fractions.

In our case, a is 2, b is 7, c is 7, and d is 1. This is because we want to multiply 2/7 by 7 to get 7 groups of 2/7. Therefore, we can substitute these values into the formula:

2/7 × 7/1 = (2 × 7) / (7 × 1) = 14/7

The result is a fraction 14/7, which can be simplified to 2. This means that 7 groups of 2/7 is equal to 2. To simplify this further, we can say that if we divide a whole into 7 equal parts, each part is 2/7. If we have 7 of these parts, we have the whole.

To graph the inverse equation f(x) = 4x - 1, we can follow these steps:

Replace f(x) with y:

y = 4x - 1

Switch the x and y variables: x = 4y - 1

Solve for y:

y = (x + 1) / 4

The graph of the original function f(x) = 4x - 1 is a line with a slope of 4 and a y-intercept of -1.

The graph of the inverse function is the reflection of this line over the line y = x, which means that the x and y coordinates of each point are swapped.

To plot points for the inverse function, we can choose some values of x and find the corresponding values of y using the equation y = (x + 1) / 4. For example:

The point estimate of the population mean is 10.5.

The point estimate of the population standard deviation is 3.240, rounded to 3 decimals.

The margin of error for the estimation of the population mean with 95% confidence is 3.1

The 95% confidence interval for the population mean is [7.4, 13.6]

a. The point estimate of the population mean is the sample mean.

We can calculate it by adding up all the sample values and dividing by the sample size:

(10 + 8 + 12 + 15 + 13 + 11 + 6 + 5) / 8 = 10.5

Therefore, the point estimate of the population mean is 10.5.

b. The point estimate of the population standard deviation is the sample standard deviation. We can calculate it using the following formula:

s = √Σ(xi - x)² / (n - 1) ]

Plugging in the sample values, we get:

x = 10.5

s = √((10-10.5)² + (8-10.5)² + (12-10.5)² + (15-10.5)²+ (13-10.5)² + (11-10.5)²+ (6-10.5)² + (5-10.5)²) / (8 - 1) ]

s = 3.240

c.

margin of error = t-value × (sample standard deviation /  √(sample size))

Plugging in the values we found, we get:

margin of error = 2.365 × (3.240 /  √(8))

margin of error=3.067

d. Finally, we can use the following formula to find the 95% confidence interval for the population mean:

confidence interval = sample mean ± margin of error

confidence interval = 10.5 ± 3.067

confidence interval = [7.4, 13.6]

Therefore, the 95% confidence interval for the population mean is [7.4, 13.6]
